2  Work Experience

• Respond to user requests and infrastructure emergencies in a timely manner.
• Maintain disk storage systems with an aggregate of five petabytes of usable space.
• Designed IBM Tivoli Storage Manager (TSM)-based backup/archive tape system, and scaled it to eight petabytes over time.
• Designed Environment Modules-based software management system to make platform differences and software upgrades transparent to our end users, scalable to multiple platforms and over one thousand package versions, with a bare minimum of configuration for each version.
• Write scripts to automate tasks internally for the system administration group and externally for users.
• Maintain approximately 100 servers, including file, database, and web servers. Maintain approximates 500 cluster nodes and the associated schedulers and resource managers.
• Analyze and solve performance problems at the software and hardware levels.
• Implemented and maintain a Nagios network monitoring system for thousands of hosts and services.
• Write and maintain documentation for complex software and hardware systems.

• Migrated the BCCD from the BBC to the Debian Linux distribution, culminating in the release of BCCDv3.
• Wrote automated build process to improve reliability of BCCD releases, and ported the build process to a continuous integration system.
• Respond to user requests for additional software and hardware support, and provide support for instructors using BCCD.

• Administered eight FreeBSD and Linux servers.
• Maintained approximately 30 Red Hat Linux clients using disk imaging systems, and three 16-node Beowulf x86/PPC clusters.
• Maintained building data/voice wiring, including a 600-port wiring closet.
• Provided end-user support for approximately 25 faculty and students from the Mathematics, Physics, and Computer Science departments.
• Setup Nagios network monitoring to enable rapid notification of system faults.
• Setup a request tracker ticket system to keep track of problems and user requests.
• Redesigned tape-backup scheduling script to support tape rotation and error notification.
• Trained new staff in the use of the administrative tools used on each of the supported operating systems, and created documentation for common tasks.
• Requested quotes for new equipment and submit proposals to the department.

• Benchmarked distributed/clustered molecular dynamics package to develop canon for further testing.
• Assisted in implementation of the x86- and PPC-based LittleFe portable concept computational clusters.
